====We have installed and been using iRedmail successfully for about 2 weeks.

Our web software (that we built) uses the iRedMail server to send and receive email by SMTP. Yesterday our application server started failing to connect to iRedmail - only for the collection of mail, symptoms are:

- server can continue to send email through iRedMail
- server just fails to collect the email
- our server is set to make the connection to iRedMail every 30 seconds
- it was working successfully for 2 weeks, no other changes on the server
- if we simply reset the password it successfully re-establishes the connection and collects the mail again

Does iRedMail have some type of "lock-out" due to our server trying to connect every 30 seconds?
Is there some log we can review to see why it might be stopping the connection?
Is there a config setting we can change to stop this behaviour?

Thanks
